Lawn Mower Battery Guide – Maintenance and Features

How do I take care of my lawn mower batteries?

Even if you are meticulous about taking care of your gardening equipment, batteries can only last so long. The average life span of a lawn mower battery is around three years. However, you can stretch the productive life of the lawn mower battery with the following tips.

Charge

Not just the leading brands, even small-time brands only manufacture Sealed Lead Acid (SLA) batteries. Such batteries require a regular charge cycle. 

If they are not charged regularly, then the fluids inside the battery begin to crystallize. Batteries lose their capacity to stay charged once the crystallization process begins.

How can I avoid this?

A maintenance charger can keep the battery fresh even when it is in storage. If the battery is completely drained, there is a chance it can still be revived with a charge. But you must bear in mind that its time may be up anytime soon.

Keep the terminals clean

The sun is out, and the grass has begun to green up and grow once again. You hop lawn mower and turn the key. Nothing? Not a click? Not a whir? And definitely no fire! 

Your mowing day is likely, to begin with, a bit of frustration. Corroded battery terminals can prevent the lawn mower from starting.

How can I avoid this?

You can use a terminal cleaner or a wire brush to clean heavy corrosion off the battery terminals. However, as they say, prevention is better than cure. 

It is best to prevent corrosion from building up. Use an anti-corrosion gel to seal the battery terminals to keep them safe from exposure to air and moisture.

Loose frayed and burned connections

If the terminal connections are loose, the signs can be similar to those of a faulty battery. Furthermore, it can lead to lead to corroded wires and terminals as well as low charge rates. 

If the wires are corroded, frayed, or burned, then the starter will not get the current it needs to function. Additionally, the battery will not get the power it needs to stay charged.

How can I avoid that?

Though most batteries these days are maintenance-free, it is still a great idea to run periodic checks on the battery terminals and other connections. 

Ensure the terminal connections are tight. When you are replacing the battery, you may also want to replace the battery cable fasteners. In the case of frayed and burned wires, which cannot be held together with electrical tape, it is best to replace them. 

It will always serve you well to repair or replace faulty connections and components to prevent further damage.

Keep the battery filled

If you are using an old battery model or one of those rare new models that require looking after, the chances are that you need to check the water level and keep it adequately filled. 

Usually, such lawn mower batteries come with a removable cap that makes it easy to check the water level and to refill it. When filling water in the lawn mower battery, you must keep in mind not to fill it with tap water. 

Tap water contains minerals, which can cause potential damage to the battery. You must always use distilled water to refill the lawn mower battery.

Invest in the perfect match

Just like automobiles, there is a suitable battery out there for your lawn mower. Usually, garden equipment such as lawn mowers uses both six volts and twelve volts batteries. 

If the replacement battery you have purchased is too large to fit in the lawn mower, it is quite likely that it will not perform well either.

How can I avoid this?

The brand and model of the lawn mower battery is usually mentioned on it. If you are unable to get a replacement battery from the same brand, there are many variants available, which will work fine. 

If you do a little research, leading e-commerce websites to have many replacement batteries with information on which lawn mower the particular battery is best suited for. This will help you narrow down your choices to a great extent. 

Points to Keep in Mind When Buying a Lawn Mower Battery

If your lawn mower battery has finally given way and it is time for you to buy a new one, then you must consider a few factors besides voltage compatibility and battery size before making the purchase.

CCA Rating

If you live in a place where it gets extremely cold during winters, you will want your lawn mower battery to have a good CCA rating

Cold Cranking Ampere, commonly referred to as CCA, is gauged by how current the battery can create in thirty seconds in temperature as low as zero degrees Fahrenheit.

 Terminal Placement

The terminals are located on the sides of the battery. Prior to purchasing a replacement battery, ensure that you know the correct terminal position needed for your lawn mower. 

If the positive terminal is on the right side of your lawn mower, then the positive terminal on the battery must also be on the right side. 

Attaching the cables within incorrect placement (positive terminal on the lawn mower with the negative terminal on the battery) can cause damage to the lawn mower and the battery.

Construction

Previously, metal plates were used in batteries. Newer models use lead plates. Batteries that have lead plates often face problems such as loss of charge and corrosion. 

The application of calcium provides the battery with a better tolerance to resist these problems.

Conclusion

There are many excellent lawn mower batteries on the market. Every lawn mower battery that we reviewed above is excellent in terms of battery life and stability. 

If you are looking for a leak-proof, stable and low-maintenance battery for your lawn mower, then the PowerStar Lawn mower Battery is an excellent choice.
